Hi, I can help with no 3.... I had the same problem two weeks ago and it’s common...
A clip breaks usually.... there’s a clip part no 11a4829cp (19) which breaks and needs changing. 1 min job to swap.

Have a look at that clip to the right of the fuel filler hole when the flap is open

Hi Ahmad,

Is the car going into limp mode when the check engine light goes on? Or is the reduced speed due to other reasons?

TPMS fault... Probably needs new sensors (they have a finite life due to batteries), or maybe the last time tires were changed, sensors were not installed at all.

As for the check engine fault, impossible to diagnose unless you can provide the codes. Get a cheap OBD-2 reader, plug it in when the light comes on, and tell us the codes that come up. As for the 40MPH limit, usually the display will say "limp home" or something if it's reduced speed. Have you checked oil levels in the transmission? Low transmission oil will trigger limp home. However, could be anything really - need those OBD-2 codes!

Thanks!

Z.

Hi Ahmad,

Do you have a higher resolution version? That image is tiny and when I zoom in it just becomes blurred. Codes are normally something like "P0048" or something. Hex codes (like "FF,07", etc) are usually PID's for pulling specific info back. If the check engine comes on, there should always be a P-code as well. It could be something as simple as a vacuum sensor (My BMW M3 at one time would drop in to limp home even if I was driving along at 80mph - suddenly all the power was gone. Pretty dangerous actually - turned out to be a simple vacuum sensor that was working intermittently).

As for the sensors, I believe you need the Huf RDE048V21 sensors. You should be able to buy them online. They shouldn't need programming, though I've not changed them personally on a 650S so not 100%. If you go here http://products.intellisens.com/ you can search, and you'll see it says the RDE048V21's do NOT need programming.

Thanks!

Z.
